@Grow4Releaf, yeah, I too love comparing different growstyles and equipment. Also like seeing someone else growing hydro... found @PatriciaGant, growing on DWC with rain water! Very interesting, looking forward to see this grow!

Good luck , been fun seeing all the different styles ppl will be growing. Have some fun with them, can't wait to see how everyone's doing in a few weeks !!

Good luck 🍀

God Luck for the cup 🍵

@PatriciaGant, Nice! I take it directly from the sink. Keep it simple/natural. From my side I try adding citric acid. With rain water you should have problems with algae and other organisms... you can try adding hypocloric acid to desinfect the rainwater... but I guess I can not talk you into some experiments with the cup grow ;)

@PatriciaGant, I run ph 5,5 for rooting and 5,8 for flowering (5,6 to 6,0)...?! ORP is oxidisation potential for fluids. Search google for hypochloric acid (DanChlorix) and try killing algea without killing the plants ;) My personal max is now 2ml/l for root fungae. Algae was an initial issue I had on perlite.

You are using DWC with PH 6,5? What is your ORP (Algae on Clay)?
